WISCONSIN FLOW REPORT

Last Updated: December 25, 2025

Wisconsin's myriad rivers and streams present a diverse range of conditions as we examine the latest streamflow data, which reveals both areas of concern and points of interest for water enthusiasts. Notably, the Bois Brule River at Brule has seen a significant rise in streamflow with a 53.78 cubic feet per second (cfs) increase in the last 24 hours, although it remains below the normal at just 19.18 percent of its average flow, suggesting potential for whitewater activities but caution for those unprepared for swift changes. On the other end of the spectrum, the Bad River near Odanah has experienced a decrease in streamflow, now at a concerning -39.75 percent of its typical level, which could affect activities and ecosystems reliant on steadier flows. Major cities along these waterways, including Sheboygan, Manitowoc, and Oshkosh, should stay alert as streamflow variations could impact water-based recreation and local water resources.

In the Fox River basin, the Fox River at Oshkosh records a high streamflow of 4230 cfs, although this is a decrease from the previous day, with water enthusiasts noting a lower than normal percent normal flow rate of -9.85 percent. Similarly, the Wisconsin River at Muscoda flows at a robust 9560 cfs, though it has seen a slight uptick of 2.36 percent in the last day and remains at -12.53 percent of the norm. Residents and visitors to these areas, including those interested in the popular whitewater trails in the region, should monitor gage heights and streamflow changes closely. For example, the Saint Croix River near Danbury has seen a substantial increase of 112.9 cfs and stands above normal at 12.4 percent, indicating potential for more vigorous conditions ideal for seasoned paddlers. These data points underscore the dynamic nature of Wisconsin's waterways, and while they currently present opportunities for adventure, they also warrant vigilance to ensure safety and the protection of local aquatic environments.
